To all wlwmzt may concern.

Be it known that ll, Gronau H. Fonsr'rn a citizen ot the United States., residing at Chicago. inthe county of Cook and State of illinois, have invented certain new and useful improvements in Disk-Wheel Assemblies, of which the following is a specihcation.l

My invention relatesto disk wheel construction and has reference particularly to the brake drum, hub and disk assembly..

'lhe objects ot the invention are, rst9 todrawing serving as a basis tor a somewhatIf detailed description in this specification.

ln the drawings- 1 l? i 1 is a fragmentary radial section ot a dis wheel adjacent the hub illustrating one embodiment or the invention; i

llig. 2 is a iront view ot a .portion ot Fig. 1 with certain parts of the disk and iront hub plate broken away; and

lFig. l3 is `a fragmentary radial section, similar to Fig. 1., showing another embodiment ot' the invention.l

Having particular referencev to Figs. 1'

and 2 ot the drawin ,the hub of the wheel is indicated at 11 lBlanges 12 and 13, which may be removable or integral. -The disk body oli the wheel isl indicated at 1t having its central portion at the hub zone lying immediately to the near oiiithe liront hub dange 12 as shown at 1.59KA while outwardly ibo ond the hub zone the disk is shown as orwardly concave.

Behind the main d 1t is disposed a disk supporting member 16 bearing against. the rear ot the disk in its deepest portion. This disk supporting member, adjacent the hub zone, is termed. into pocket portions 16a and 1t which are odset to the iront and rear9 the iront portions continuing inwardly in bearing contact with the disk and opposite the front hub tlange 12., and thence again rearwardly and inwardly to an abut airing iront and rearL `tion 15 ment against the iront face ofthe rear dange 13 at the huh. Thus the portions i6 ot the disk supporting memr extend rearwardly trom the point oi odset and lic against the iront tace ot the haed flange 13. The portions 16 are tixedly secured to the rear hub flange 13 by means of short bolts ll while longer attaching bolts 18 transx the .lined hub da 13, the disk supporting portions 16 and 16, the disk portion 15 and the removable hub ,dange 12, all of these parts being iirmly clamped together by means ot the nuts 19 acting upon said attaching bolts. llt will be observed that the tor ne of the hub 11 istransmitted directly to t e member 16 by means oi' the portions 16b through the bolts 17, and is then transferred trom the portions 16 ot the member 16 to the disk proper ot the wheel. through the connection oi 16 and 15 by the bolts 18.

ln the case ot the rear wheel the disk supporting member it forms the iront wall oi the brake drum 2U which contains the brake B0 y adjusting mechanism, a portion of which Kis indicated at 21. The concentrically disposed brake bands are indicated at 22 and 23 with their friction liners 22a and 23@L acting upon the double coned periphery 2t ot the d. 85

llhe iront wall iti of the brake drum is provided with a manhole 25 at a position to t ready access to the brake mechanism within the d. This opening 25 is normally closed by the wheel disk when hangs 12st ereby uncovering the opening 25. 95

lin Fig. 3 ot thev drawing, a form ot construction is illustrated -which includes a twoart hub comprising the demonntable portion 26 and the hired portion 27 having integral radially dnt/ed portions at 28 whic provide a driving interlock between the two9 thus taking the, shear from the bolts 2t which transha the rear hub dange 30 and the liront hub flange 31. The hub portion 27 has a radial' extension 32 which forms e tillor or acing member between the poropthe disk md thehub dange 30. Here the brake drum is shown as a cylindrical member 33 closed at the iront by a dat wall having an opening formed by the rear hub tlare 30 and having an opening 3ft therein. nshings 35 and 36 about the lil@ ica

through the opening 34 to the brake drum interior as in the former case.

4I claimt I p 1. In a disk wheel, the combination with the hub, of a disk demountably secured thereon, and a` brake drum also secured to the hub at the rear of the disk` and having a front opening normally obstructed by the disk when on the hub and through which access may be had to the interior brake `mechanismwvhen the disk is demounted.

2. In a disk wheel, the combination with a hub, of a disk demountably secured thereon, and a brake drum also secured to the hub at the rear of the disk and having an opening in its front wall which opening is normallv closed bv the disk when on the hub and through which access may be had to the interior brake mechanism when the disk is demounted.

3. In a disk wheel, theecombination ofa hub having front and rear flanges spaced apart, a disk body disposed in the hub zone at the rear of the front flange, and a disksupporting member bearing on the rear of the disk outwardly of the hub zone and having portions laterally offset towards the front and rear within the hub zone and bearing respectively one against the rear of the disk opposite the ,front flange and the other againsty the front of the rear flange, and attaching bolts transfxing the two flanges and the interposed disk and certain of the offset portions of the supporting member.

4. In a disk wheel, the combination of a hub having front and rear flanges spaced apart, a disk body disposed inthe hub zone at the rear of the front flange, and a disksupport-ing memberbearing on the rear of the disk outwardly of the hub zone and having portions laterally offset towards the front and rear within the hub zone and bearing respectively one against the rear of the disk opposite the front flange and the othex` against the front of the rear flange, bolts securing the last mentioned portions to the rear flange, and attachingbolts transfxing the two flanges and the interposed -disk and forwardly offset portions of the supporting member.

5. In a disk wheel, the combination of a hub having front and rear flanges spaced apart, a disk body disposed in the hub zone at the rear of the front flange, and a brake drum having its front wall formed as a disksupporting member bearing on the rear of the disk outwardly of the hub zone and having portions laterally Voffset towards the front and rear within the hub zone and bearinxg respectively one against the rear of the disk opposite the front flange and the other against the front of the rear flange, bolts securing the last mentioned portions to the rear flange, and attaching bolts transfixing the two Vflanges and the interposed disk and forwardly offset portions of the supporting member. i

6. In a disk wheel, the combination of a hub having front. and rear flanges spaced apart, a disk body disposed inthe hub zone at the rear of the front flange, and a brake drum having its front wall formed as av disk-supporting member bearing on the rear of the disk outwardly of the hub zone and having portions laterally offset towards the front and rear within the hub zone and bearing respectively one against the rear of the disk opposite 'the front flange and the other against the front of the rear flange, bolts securing the last mentioned portions tothe rear flange, and attaching bolts transfixing the two flanges and the interposed disk and forwardly offset portions of the supporting member, the brake drum having an opening in its front wall normally closedby the disk when on the hub and through which access may be had to the interior brake mechanism when 'the attaching bolts are released and the disk is demounted.

' In testimony whereof I have hereunto subscribed my name.
